American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 February 4, 2004 RE: FCC ID: QU4-XWT380 Attention: Mike Royer I have a few comments on this Application. 1. Please note that no letter of confidentiality has been provided, thus all exhibits will be open for public view. If you wish confidentiality of the schematics, block diagram and theory of operation, please submit a request for confidentiality letter. 2. Please note that the picture on the bottom of page 2 and the picture on page 4 appear to be the same picture. Please show the other side of the circuit board in these pictures.. 3. Please note that recent interpretations from the FCC have reiterated that the operational description of a device is to include a brief explanation of how the device actually works and not simply an overview of the purpose of the device. Please provide an operational description of the intentional radiator part of this device that explains how the device works. 4. Please show how you derived the ”averaging factor” shown in the data sheets (i.e. plots of the duty cycle over 100ms and the calculation etc). 5. Please provide the peak readings for the spurious emissions averaged on page 18 of the report. 6. Please provide evidence that the device meets the automatic or manual turn off requirements of 15.231a2&3. This is generally done in the operational description.
